What Is a Suction Filter?
Unlike high-efficiency hydraulic filtration components like return-line or pressure filters, suction filters are intentionally designed with larger mesh openings (typically 100–200 microns). This is critical: too fine a filter at the suction side can restrict flow, leading to cavitation—a destructive phenomenon where vapor bubbles form due to low pressure and then implode inside the pump, eroding metal surfaces over time.
